Using nonthermal plasma (NTP) to promote CO2 hydrogenation is one of the most promising approaches that overcome the limitations of conventional thermal catalysis. However, the catalytic surface reaction dynamics of NTP-activated species are still under debate. The NTP-activated CO2 hydrogenation was investigated in Pd2Ga/SiO2 alloy catalysts and compared to thermal conditions. Although both thermal and NTP conditions showed close to 100% CO selectivity, it is worth emphasizing that when activated by NTP, CO2 conversion not only improves more than 2-fold under thermal conditions but also breaks the thermodynamic equilibrium limitation. Mechanistic insights into NTP-activated species and alloy catalyst surface were investigated by using in situ transmission infrared spectroscopy, where catalyst surface species were identified during NTP irradiation. Moreover, in in situ X-ray absorption fine-structure analysis under reaction conditions, the catalyst under NTP conditions not only did not undergo restructuring affecting CO2 hydrogenation but also could clearly rule out catalyst activation by heating. In situ characterizations of the catalysts during CO2 hydrogenation depict that vibrationally excited CO2 significantly enhances the catalytic reaction. The agreement of approaches combining experimental studies and density functional theory (DFT) calculations substantiates that vibrationally excited CO2 reacts directly with hydrogen adsorbed on Pd sites while accelerating formate formation due to neighboring Ga sites. Moreover, DFT analysis deduces the key reaction pathway that the decomposition of monodentate formate is promoted by plasma-activated hydrogen species. This work enables the high designability of CO2 hydrogenation catalysts toward value-added chemicals based on the electrification of chemical processes via NTP.

“…This is because CaCl 2 is the salt of a strong acid while carbonic acid is a weak acid. Therefore, to create conditions conducive to CO 2 absorption and the formation of carbonate ions in the solution, an absorption promoter, such as amines or ammonia, should be added to facilitate the CO 2 transfer from the gas phase into the liquid phase [37,46].…”

Technologies for the management of various types of waste and the production of useful products from them are currently widely studied. Both carbon dioxide and calcium-rich waste from various production processes are problematic wastes that can be used to produce calcium carbonate. Therefore, the purpose of this paper is to provide an overview about the state of the development of processes that use these two wastes to obtain a valuable CaCO3 powder. The paper reviews the current research on the use of post-distillation liquid from the Solvay process, steelmaking slag, concrete, cement, and gypsum waste as well as some others industrial Ca-rich waste streams in the calcium carbonate precipitation process via carbonation route. This work is an attempt to collect the available information on the possibility of influencing the characteristics of the obtained calcium carbonate. It also indicates the possible limitations and implementation problems of the proposed technologies.

Improving the rate of mineralization reaction in alkaline solid waste, primarily consisting of calcium carbide slag, is essential for mineralization plugging, fire prevention, and extinguishing. In this study, a novel method to synergistically enhance the mineralization reaction rate by adding catalytic CO 2 conversion substances and increasing the gas−solid contact area was proposed. A high-temperature and high-pressure reactor device was used for the test, and the effects of four factors on CO 2 conversion, namely triethylenetetramine (TETA) addition, CO 2 initial pressure, calcium oxide (CaO) addition, and reaction time, were tested by single-factor and response surface curve analysis. According to the influence of the absorption capacity, the optimal combination of the CO 2 adsorption capacity was screened out. Through the chemical composition and phase analysis of carbide slag before and after the carbonation reaction, it was observed that effective calcareous components existed in the forms of Ca(OH) 2 and CaCO 3 , verifying that carbide slag can effectively mineralize and store CO 2 gases. The mechanisms underlying TETA storage and CO 2 conversion were studied by density functional theory calculations. Furthermore, the TETA solution and carbide slag were compounded and foamed to prepare a threedimensional porous gel to study its influence on the mineralization efficiency of CO 2 . The results showed that the potential to fix CO 2 at different temperatures is 0.07 g/g CO 2 (20 °C), 0.077 g/g CO 2 (30 °C), and 0.110 g/g CO 2 (40 °C). The economic benefit analysis showed that the mineralization costs of 1 ton of CO 2 at different temperatures were about ¥15,642.39 (20 °C), ¥14,220.35 (30 °C), and ¥99544.25 (40 °C), respectively. More importantly, the porous gel was prepared using natural polymer materials and industrial solid waste, thus offering an environmentally compatible approach to provide a theoretical basis for the research and development of materials for preventing coal spontaneous combustion.
